All models will effectively regulate under no-load conditions (with perhaps a slight increase in output ripple/noise). See Technical Notes/Performance Curves for additional explanations and details. Input Ripple Current is tested/specified over a 5-20MHz bandwidth with an external 33μF input capacitor and a simulated source impedance of 220μF and 12μH. See I/O Filtering, Input Ripple Current and Output Noise for details. The Current-Limit-Inception point is the output current level at which the converter’s power-limiting circuitry drops the output voltage 3% from its initial value. See Output Current Limiting and Short-Circuit Protection for more details. See Dynamic Load Response for detailed results including switching frequencies. For Start-Up-Time specifications, output settling time is defined as the output voltage having reached ±1% of its final value and the load current having reached at least 80% of its final value. MTBF is calculated using TELCORDIA SR-332 Method 1 Case 3, Issue 1, ground fixed, +30°C ambient air and full-load conditions. All models are fully operational and meet all published specifications, including “cold start,” at –40°C. The highly unlikely, simultaneous failure of several specific on-board components could result in the MAPC-104’s input voltage appearing at its output, despite the unit’s output overvoltage protection mechanisms. In this rare situation, the Power Good signal (IPH pin 2, Pwr_LED_Drive) will be deactivated and systems monitoring Power Good will eventually shut down. If you are using an MAPC-104 to power a load that must be protected against any and all possible overvoltages, no matter how rare, you will have to provide the protection external to the MAPC-104. Please contact MPS for recommendations.

Devices can withstand sustained output short circuit. These are stress ratings. Exposure of devices to any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the Performance/ Functional Specifications Table is not implied. Connector Designations The official PC/104 bus specification identifies the standard interboard bus connections as paired J1/P1 and J2/P2 on one side and J3/P3 on the other side. However, J1/P1/J2/P2 is physically all one big 4-row connector with J1/J2 bus receptacle sockets (female) on the top side and P1/P2 pins (male) on the bottom. This arrangement provides interboard pass-through connections between PC/104 boards. MPS refers to this single connector as “J1.” MPS’s auxiliary connectors (the IPH and the 5V Auxilliary Power Connector) are internally designated P1 and P2 respectively and this nomenclature may appear on the board silkscreening. This is purely an artifact of automated sequential part numbering in our CAD system and has no relation to the standard PC/104 interboard bus connectors. Don’t get the connectors confused since they are all very different types and locations! www.murata-ps.com/support MDC_MAPC-104.B02 Page 4 of 7 MAPC-104 PC/104-Plus Series Non-Isolated, DC/DC Converters 3.3, 5.1 & 12.4, 46W Mobile Applications Typical Performance Curves 3.3VOUT Efficiency vs. Line Voltage and Load Current (5.1V @ 5.46A and 12V @ 0.07A) Efficiency vs. Line @ 46W 94 94 93 93 92 92 91 91 VIN = 9V Efficiency (%) Efficiency (%) VIN = 12V 90 89 VIN = 24V 90 89 VIN = 32V 88 88 87 87 86 86 9 12 18 24 28 32 0 1.25 Input Voltage (V) 2.5 3.75 5 6.3 0.08 0.1 Load Current (Amps) 5.1VOUT Efficiency vs. Line Voltage and Load Current (3.3V @ 5A and 12V @ 0.07A) 12VOUT Efficiency vs. Line Voltage and Load Current (5.1V @ 5.46A and 3.3V @ 5A) 94 94 VIN = 9V 93 93 VIN = 9V 92 91 Efficiency (%) Efficiency (%) 92 VIN = 12V 90 VIN = 24V 89 91 VIN = 12V 90 VIN = 24V 89 VIN = 32V VIN = 32V 88 88 87 87 86 86 0 1.25 2.5 3.75 Load Current (Amps) 5 6.3 0 0.02 0.04 0.06 Load Current (Amps) www.murata-ps.com/support MDC_MAPC-104.B02 Page 5 of 7 MAPC-104 PC/104-Plus Series Non-Isolated, DC/DC Converters 3.3, 5.1 & 12.4, 46W Mobile Applications Self-Protection Features The MAPC-104 contains two systems for protection of out-of-limit voltages, currents and temperature. These systems control two output lines located on the Input Power Header connector. Both systems operate independently and concurrently. The MAPC-104 will respond to both temperature and voltage/ current simultaneously. The output circuits for both these controls are shown below. Both of them will drive either an external LED lamp and/or a logic circuit. The Overtemperature Warning Circuit assumes that an external pullup resistor is supplied by the user. The Power Good Circuit (“Pwr_LED_Drive Out”) includes an on-board pullup resistor to drive an external LED with about 15mA. /4?7ARN/UT HI (transistor off) = Power is normal. LED lamp is illuminated. LO (transistor on) = Power fault, LED lamp is dark Overtemperature Operation The overtemperature system includes a on-board temperature sensor, a local microcontroller with A/D inputs, a timer and hysteresis so that the user may take steps to prevent inadvertant shut down. Operation proceeds as follows: If the on-board temperature exceeds +115°C, the OT_Warn Output is asserted (LO) by the microcontroller and an internal 30 second software timer is started. The outputs remain powered on. If the 30-second timer has not expired and the on-board temperature cools below +110°C, the OT_Warn Output will be deasserted (HI) and operation will continue unchanged.  #/.42/,,%2 --"4 M7 MAXIMUM n6). Pwr_LED_Drive Out (pin 2, pullup to internal +5V): If the 30-second timer has expired and the temperature still exceeds +115°C, the outputs will shut down. As soon as the on-board temperature cools to less than +110°C, the MAPC-104 will automatically restart and power will be restored to the outputs. #/--/.

The Pwr_LED_Drive Output is indirectly controlled by the on-board microcontroller. The on-board PWM switching controller measures +3.3V and +5V output voltages and all output currents. The microcontroller measures input voltage and the +12V output voltage. The system requires that the input voltage is within normal tolerances at all times. If the input voltage is too high very briefly at startup (but not exceeding the absolute input voltage), the system will start normally if the input voltage reaches acceptable limits quickly (under half a second). This typically occurs as a load is applied. When the system first starts, the Power Good LED (if installed) remains dark briefly until all on-board startup conditions are met (less than half a second) at which point the LED is illuminated. The operation proceeds as follows: If the fault condition remains, the system will attempt to restart two more times, spaced about half a second apart. If the fault remains for the third time, the system will shut down and will not retest the fault. The system must now be restored by fully cycling the input power. The 3-fault countdown only occurs if the fault does not recover continuously throughout the attempted restart interval. An occasional random shutdown and successful restart will not trigger the 3-fault counter. However, external logic should record the frequency and quantity of such shutdowns. RoHS-5 compliance refers to the exclusion of the six hazardous substances in the RoHS specification with the exception of lead. MPS’s RoHS-5 products use all the conforming RoHS materials, however our solders are Sn63/Pb37. If the outputs on any lines deviate from approximately ±7% of nominal and/or the output current is excessive, the outputs are all shut down and the Pwr_LED_Drive Output is desasserted (LO, lamp dark). The system will attempt to restart in about half a second by briefly turning on all outputs. If successful and the fault is eliminated, the Pwr_LED_Drive Output will be asserted (HI, lamp lit) and operation continues.
